Set of 4 fused glass coasters in Green adventurine glass with a border of white art glass. The adventurine glass has a sparkle that catches the light. Perfect for house warming gifts or holiday gift. 3.5" square. Food safe Rubber bumpers are on the bottom corner of the dish for stability on your table. Hand wash only. Food safe. Each piece is personally handmade by me in my New York studio using several layers of art and/or dichroic glass. These layers are cut, fused together, shaped, and fused again to achieve a unique and in most cases a one of a kind design. Each piece is examined to insure the very best for you. All fused glass has been properly annealed for strength and durability.
